Abstract
Disclosed herein is a semiconductor device comprising local bit lines, a global bit line, local switch control lines, main switch control lines, hierarchical switches controlling electrical connections between the local bit lines and the global bit line in response to potentials of the local switch control lines, local switch drivers driving the local switch control lines in response to potentials of the main switch control lines, and main switch drivers selectively activating the main switch control lines.
